Dragonflies are masters of using the ipsilateral wing-wing interaction for different kinds of flying modes. It has been discovered that the phase difference between ipsilateral forewings and hindwings plays important role on wing aerodynamic performance. In the current study, we continue our research of a modeled dragonfly in slow flight (Liang and Dong (2009)) by varying the phase difference between the forewings and hindwings and look at the changes of aerodynamic performance of hindwings. Results of this work will help with the design of quadwinged MAVs.

A numerical study on the aerodynamic performance of a two-dimensional flapping wing in asymmetric stroke in hovering and forward flight is carried out. The effect of the asymmetry of the stroke on aerodynamic forces and flow structures of the wing is analyzed. It is found that for hovering flight appropriate asymmetric stroke can enhance the aerodynamic performance of the wing at low Reynolds number, but it may not be functioning at moderate and high Reynolds numbers. For forward flight the asymmetric stroke does not increase the lifting efficiency and propulsive efficiency of the wing simultaneously. However, it influences the time history of the aerodynamic force significantly, which may enhance the flight maneuverability of the wing. The present results provide physical insight into the understanding of aerodynamics and flow structures of insect flight with asymmetric stroke.
